Socket 3/8" 6-point 18mm Proxxon PR23523

Proxxon 3/8" 6-point 18mm socket is a hand tool intended for use with 3/8-inch drive ratchets and torque wrenches. Engineered to engage 18 mm hex fasteners, the 6-point configuration delivers firm contact on flats to minimise rounding and improve torque transfer. The socket is suitable for workshop, automotive maintenance and general mechanical tasks where reliable fastening and controlled torque application are required.

Advantages

The 6-point design offers secure grip on hex fasteners, reducing the risk of slipping and rounding compared with 12-point alternatives. Compatibility with 3/8-inch drive tools ensures broad usability with common ratchets and torque wrenches. The socket’s dimension and geometry provide consistent force distribution across the fastener flats, supporting accurate torque application and repeatable results.

Suitable for

• Automotive repair and maintenance (wheel, engine and chassis fasteners compatible with 18 mm)
• Workshop assembly and disassembly of mechanical components
• Professional and hobbyist mechanical work requiring controlled torque

Key specifications

• Drive size: 3/8-inch
• Point configuration: 6-point (hex)
• Socket size: 18 mm
• Typical applications: hex fasteners in automotive and workshop use
• Use with: compatible ratchets and torque wrenches

How to use

Select a compatible 3/8-inch drive ratchet or torque wrench and fit the socket onto the drive square until it clicks or seats securely. Place the socket squarely over the 18 mm hex fastener so the 6-point faces align with the flats. Apply torque gradually and keep the tool aligned with the fastener axis to avoid cam-out. When using a torque wrench, set the required torque value and tighten until the wrench indicates the target torque. Remove the socket by pulling it off the drive square when work is complete.

Usage recommendations

Inspect sockets regularly for wear, cracks or deformation before use. Use the 6-point socket for fasteners in good condition and avoid excessive impact with air tools unless the socket is rated for impact use. Use proper personal protective equipment and follow torque specifications from component manufacturers.
